The nearest airport is Liberia, roughly 1.5 hours away by car. The nearest city is La Cruz which is 25 minutes away, and the nearest town with a small supermarket is El Jobo, 8 minutes away by car. From San Jose or Liberia simply take the Interamerican Highway north until you reach La Cruz (about 15 kms before the Nicaraguan border). Make a left off the highway. You'll pass the La Cruz park on the left when you're crossing the town, just continue straight on to El Jobo.

The road will become a dirt road after you wind down the mountain immediately after La Cruz. Keep going for 10 kilometers more and be on the lookout for a small PLAYA COPAL sign on the right. There's a house at that corner and a small stone fence you can use as a reference. Then drive 1km directly to the beach.
